P-3k is a three-phase surge arrester type 3 according to EN 61643-11 suitable for use in TNS, TNC and TT systems. These are parallel devices intended for protection of electronic appliances against impulse surge. All varistors in P-3k device are fitted with thermal fuses to prevent short and also permanent overloading. P-3k units are to be connected as near to the protected electronic appliance as possible.
The right function of P-3k230, P-3k400 and P-3k500 devices is indicated by three green LED diodes.
The function failure of P-3k230 DS and P-3k400 DS devices is indicated by target disconnection of mechanical thermal fuses which react to varistors overheating above c. 120°C. If one of the three thermal fuses reacts, the non-potential contact FAILURE disconnects at the same time (in case of DS version only).
Function of remote monitor terminals
When the P-3k is operating correctly, the switching contact for remote monitoring is connected. Once the thermal fuse reacts to varistor overheating the switching contact for remote monitoring will disconnect.
